I thought the same thing but was not able to get stacked images that
were as good as APS-C work, but I was just getting started with focus
stacking when I experimented with it and gave up on the Q quickly.
The issues I ran into were that that Q's sensor, even at ISO, if fairly
noisy and focus stacking compound noise. Working with flash and a 3rd
party Q to K converter was problematic because the electronic shutter
defaults to a sync speed of 1/30th. Too slow to help eliminate
vibrations. But an official Pentax Q to K converter might help with
that, since it has a built in leaf shutter.
Good luck -

Mark,
Very happy to read your considerations about macro. I had thoughts along
similar lines, but actually for extreme macro studio work. Controlling
vibration at 4X and beyond can be a pain. A setup that requires less
magnification to fill the frame could be a good thing if the image quality is
good enough. And the central shutter design and faster flash sync speed could
also help reducing vibrations.
This could be fun. :-)

I have the original Q, not the Q7. It's a fun system though I haven't
used mine in a long time. Back in the days when I traveled for my job I
took the Q kit on the road with me -camera , fisheye, normal zoom and
tele-zoom - a small, light but versatile kit.
And as an update to the copy of this reply that I accidentally sent
directly to you - the IQ is decent, more than adequate for web based
images and good enough for smaller prints, though its best to keep the
ISO as low as possible. The Q7 sensor is about 50% larger than the
original Q in terms of surface area, so the IQ should be a bit better.
IMO - one niche for the Q is for macro in the field. Let's say you have
a gnat that is 6mm from head to toe and you want a photo of it as you
are hiking along. Pull out the Q, put on a K to Q adapter and a 1:1
macro lens, shoot at f2.8 to f5.6. Very easy setup to carry and deploy
and at f 2.8 to f5.6 you could probably keep the ISO fairly low and
have
decent DOF but some diffraction limit on sharpness. But on APS-C or
full frame the gnat would need 4x to 6x magnification. Not so easy for
field work. For this kind of macro work, the Q / Q7 can let you get a
decent shot (not great) where you are not likely to get any shot at all
using APS-C or full frame.

Picked up a Q7 kit today that came at an irresistible price. Any
